Control Initial Enabled State For Dependant Controls That Are Enabled / Disabled By JQuery?
Jan 3, 2010
So far, I've seen (and I'm using the following) scripts to show/hide a div or other controls depending on another control in ASP.NET
$('[id$=myRadio_0]').click(function() { $('[id$=myDiv]').show(); });
$('[id$=myRadio_1]').click(function() { $('[id$=myDiv]').hide(); });
and of course, my div in html like
<div id="myDiv" runat="server" visible="false">
and that works fine when the user selects either option of the radiobuttonlist. However, when I assign that radiobuttonlist a value of 1 or yes on my Page_Load on code behind, that isn't (and probably can't be) caught by jQuery, and my div remains invisible even though the control has a value of Yes/1. So, do I need to set the visibility of that div from code behind, or is there a way in jQuery to force a scan of these dependencies after i've set the values for the main controls in code behind?
I have an asp.net ajax enabled form that looks like this:
[Code]....
[Code]....
As you can see in the OnPreRender event, the Save button gets enabled or disabled depending on whether the datagrid is in edit mode or not. When I step in the code, it operates correctly in the code, but it does not get reflected correctly on the screen. That is, even when btnSave.Enabled set to true in the code, the browser displays the disabled button. Any idea why this might be happening?
i have a usercontrol say "abc" in a page, in that page only i have a button to edit.In edit_Click i can not find abc.Enabled=false;how to Enable or Disable the user control
Within an ASP.NET AJAX UpdatePanel on my page I have a submit button which has some custom javascript validation applied which set a global _cancelGeneralSettingsUpdate flag depending on the results of the validation.In this case the variable _cancelGeneralSettingsUpdate is correctly set to false but the initializeRequest function is not called before the page attempts to postback via AJAX, causing the postback to fail. I need to be able to have postbacks succeed once the invalid input has been corrected and the user clicks the submit button again. Unfortunately I do not seem to be properly wired into the PageRequestManager pipeline once postback has been cancelled. If I refresh the page, everything works again, but cancelling the postback via args.set_cancel(true)
I've got a bit of a problem UpdatePanelAnimationExtenders. Here's an example of the code structure I have:
[Code]....
Now here's my problem. When dd1 triggers the postback both dd1 and dd2 get disabled (instead of just dd1) and after the request is complete only dd1 gets enabled back. The behaviour is also true the other way around (if dd2 triggers the postback both dropdowns get disabled but only dd2 gets enabled back). I'm not really sure what to make of this.
I've inherited a project and in effort to beautify it, I'm replacing an image based menu bar with a CSS based bar. When you click on a button it takes you to the appropriate page.
Currently in the OnInit() it checks what page you're on and then changes the URL of the image for the appropriate button to be the "active" image for that button:
Pretty simple, and works fine, but it's a pain to add new items, because I need to create a new image and if I want to change the look, I have to create a whole new slew of buttons.
I have built out the CSS menu using basic UL and LI and all the hovers and links work fine. My issue comes when I want to set the "active" item. The way the CSS works is by either setting the CLASS of the active item to "active" or I could easily change it to set the ID of the item to "active", but in either case the viewstate crashes on any posts because the object is not the same as it was when the page loaded, since the style is updated when the OnInit(); event goes off.
I've tried both setting the class name:
menuFacilities.Attributes.Add("class", "active"); as well as directly applying the CSS style: menuFacilities.Style.Add("background", "#1376c9 url('images/topnav_active.gif') repeat-x;");
Both work fine on the initial page load, but once I click anything that posts, it crashes with a viewstate failure.
If I set the enableviewstate="false" then it works fine between different page loads, but not if I post to the same page (ie submit a search form)
I can't figure out how to handle the "active" object. For some reason the image URL works for asp:Imagebuttons
Here's what one of the items in the menu looks like (pretty simple stuff here):
time for some expertise. I have a datalist which contains a radiobutton in the itemtemplate. This radiobutton is disabled (set enabled to false) by default. On the html output I have a checkbox, which, when ticked, enables the radiobuttons through javascript. This is all working fine. The rb's are enabled and I can check them. However when the page is posted back. The checked property is always false.
I use the code below to retrieve the value of this rb:
[Code]....
This code is working fine when the initial state of the radiobuttons set to enabled server side.
In my page, I need to enable a text box when user click on check box(checked). I have used javascript for this. It works fine but when there is postback for the page, the textbox becomes disabled again although the check box is checked. But the value in textbox still appears. Is there any method to retain the enabled state for text box on postback other than using hidden values?
[ServiceContract(Namespace = "")] [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] public class Aja { [WebGet] [OperationContract] public string Hi() { return "hi world!"; } }
and I'm trying to do this: $.get('Aja.svc?method=Hi', function(d) { alert(d.d); }); In firebug I see that the result is HTTP Error 404.17 - Not Found The requested content appears to be script and will not be served by the static file handler. I use .net 3.5, jquery 1.4.4
I have a CSS Adapter enabled Menu(having sitemap data source) which I have created using this tutorial Multi Level ASP.NET Menu with CSS Friendly Control Adapters. Now I want to load a div(containing contact info) on one of this menu item's onclick event. let me know how I can do this with jquery? Where should I add the code?
how to get the total row counts in a Gridview control with default paging enabled? My gridview control is bind to an ObjectDataSource control.
The problem I am having right now is that when I loop through the gridview control, it only contains the total row for the current page being displayed on the screen and not
the total row in the entire grid. I am using the the for each loop.
I have started a simple website using ASP.NET but it is not an AJAX-enabled project. Now what I need is to use an AJAX control specifically Autocomplete) but I do not know how to add it to my website. What I should do guys? Do I need to add something in my library? What should I do in order to see it in the toolbox?
I have a simple problem: I have a bunch of controls on a page and each one requires a validation. Also, I set control's enable=true/false programmaticaly, based on a checkbox . Now, I would like to disable the validation of a control if it is not enabled.
I am working on Add To Cart Functionality, and I have added a GridView control with paging enabled. In the GridView, I show the quantity in a text box and handle the OnTextChanged event for that textbox. Now the problem, is how can I keep the changed quantity text in session or view state, and in which row, so that I can update my GridView and bind that data again to the GridView?
Here I took GridView with id gvMaster.

I want to show changed quantity value in grid with paging enabled.
My only requirement is to find a selected pdf in a folder is Reader enabled or not, more specifically if usage rights are defined in a way that allows people to add annotations (e.g. comments).
I am doing this in windows application. If I click a button, an event is triggered searching a folder for PDF files. This event needs to check whether or not the PDFs in the folder are Reader enabled for comments. If they are, I need to remove the comment usage rights or revert the PDF back to its original version.
My code can only find PDF files in the folder. I don`t know how to check if the selected PDF is comment enabled or not.
private void button1_Click(object sender, EventArgs e) { { string[] filePaths = Directory.GetFiles("D:myfolderpdffolder"); List<ListViewItem> files = new List<ListViewItem>(); foreach (string filePath in filePaths) { ---need to check comment enabled or not--- } } }
I have 3 tabpanels. When I'm creating a new record I hide the 2nd and 3rd tab panel.
Protected Sub Page_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.PreRender If Me.hdnFileID.Value = -1 Then Me.tabInvoices.Enabled = False Me.timesheetTab.Enabled = False End If End Sub
then I have a pagemethod that saves the data. Once that is done I do this in javascript to enable the tabs so users can work on them.
//TSTab is the clientid of the tabcontainer FileTab = $find(TSTab); var tab1 = FileTab.get_tabs()[1]; tab1.set_enabled(true); var tab2 = FileTab.get_tabs()[2]; tab2.set_enabled(true);
this works but the child controls in the tab are disabled
